GB/T 15594-2010Plastics - Octahydroxy polyether polyols (English PDF)

Foreword

This standard replaces GB/T 15594-1995 "eight hydroxyl polyether polyol." The main difference compared with the standard GB/T 15594-1995 as follows:

--- Modify the scope of the content (the 1995 edition 1, edition 1);

--- 8010 canceled the product;

--- Increased 8205,8208,8306 products;

--- Modify the product requirements (1995 version 4.2, this version 4.2);

--- Canceled measured unsaturation (1995 Version 5.8);

--- Provisions of the arbitration test methods hydroxyl value and viscosity measurement (edition

--- Batch modified rules (1995 version 6.1, this version 6.2.1);

--- Modify the sampling plan (1995 version 6.2, this version 6.2.2);

--- Modify the decision rule and re-inspection rules (1995 version

6.3 and 6.6, this version 6.3);

--- Canceled before using the unit version of the acceptance and demand for arbitration (the 1995 edition

--- Modify the storage period (1995 version 7.4, this version 7.4);

--- Increase the informative Appendix A. Appendix A of this standard is an informative annex. The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee of plastic products and plastic resins General Methods Chapter (SAC/TC15/SC4) centralized.

1 Scope

GB/T 15594-2010 is the Chinese national standard on plastics - octahydroxy polyether polyols, in the field of rubber and plastic industries. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 26 September 2010 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 August 2011. Classification: ICS 83.080.20, CCS G32. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies eight hydroxyl polyether polyol 8205,8208,8305,8306 requirements, test methods, inspection rules and signs, packaging, Transport, storage and so on. This standard applies to the initiator containing sucrose in the catalyst and propylene oxide ring-opening polymerization of a polyether polyol 8205, 8208,8305,8306.
